Patent EP-0010882-B1 (EP)
IPC: H02H7/22
Filed: 1979-10-10
Granted: 1983-10-05
Abstract: A switching circuit (1) has a solid state power switch (9) which is either a PNP or NPN transistor or a VMOS p-or n-channel device. Three individual sensing circuits (2, 3, 4) are set to indicate whether a predetermined operating characteristic of the switch (9) is greater or less than a given threshold value and thus to indicate if a fault is present in the switch (9) or the load (L) it supplies. Digital logic circuit means comprising three logic circuits (5, 6, 8) produce two digital signals (D, P) from the output signals of the sensing circuits respectively indicating if a fault exists and if it is a serious fault or not. A circuit (7) comprising gating means disables the switch (9) in the event of a serious fault and a delay circuit (33, 34) is provided associated with the logic circuit means to prevent current surges due to short circuit faults being confused with normal operating current surges in switch on.

IPC: G01N15/08
Filed: 1982-06-24
Granted: 1987-01-14
Abstract: This invention concerns a method and an equipment to perform porosimetric analyses, in particular following known analyses performed by a so-called mercury methods, wherein volumetric variations of mercury placed in a vessel are recorded, said variations being due to a mercury penetration into the pores of a solid sample placed in the same vessel under mercury pressure variations. 
<??>According to the invention further analyses are carried-out by lowering mercury pressure from a maximum value substantially to ambient value, following a predetermined law in function of time, for instance and preferably a pressure reduction at constant speed, and by simultaneously detecting the volume variations of mercury which comes out of the sample pores when pressure decreases. Said detection, when performed in relation and/or in addition to the traditional one during pressure increase, allows to obtain a pressure-volume mercury curve which provides further data on the porosimetric characteristics of the sample, in particular related to the shape of the pores of same.

Abstract: In the processing of instructions in data processing systems it is not always possible to execute these instructions without interruption since particular situations, in the following called events can occur which necessitate a short interruption for executing the operations caused by such events before continuing the interrupted instruction processing. Such repetition however is only possible when the contents of the operation register containing the instruction is frozen during the interruption. Such a situation requires two actions: the first is the execution of a forced operation to resolve the event. The second action is a repetition of the instruction and execution phase of the interrupted instruction.

Granted: 1985-12-27
Abstract: A machine is of the type comprising an oscillating movable head with a tool-holding spindle, driven in rotation above a lens-support. The lens-support is borne by a vertically movable spindle which is mounted inside a sleeve, flared out at its upper part to form two bearing surfaces and, the lens-support comprises a ledge which surrounds the part of the sleeve containing the bearing surfaces. The lens-support rests on a head mounted for free rotation in a fixed pivot so that when the spindle is moved upwardly, the lens-support is immobilized in a horizontal position, to deposit the lenses to be polished thereon, or to remove them after the polishing operation. When the spindle is moved downwardly, the lens-support, then at a distance from the bearing surfaces, can oscillate freely during the lens-polishing operation, under the effect of the movable oscillating head.
